That's right, folks, we're calling it. Even though the first (official) day of the hot season is about three weeks away, we're tagging the Banana Republic Milly Collection the collaboration of the summer. Maybe it's those punchy, electric patterns and colors? Or, maybe it's the versatility of all those chic basics and well-wrought accessories? Either way, no other collabo we've seen quite captures the spirit of the season like this baby, and it's finally available in stores and onlinetoday.

To toast its arrival, BR is throwing summer soirees tonight nationwide with our very own global editor, Connie Wang, spreading some R29 love at its Rock Center store. At the Milly Mixer, you'll not only get drinks and first dibs on all those garden-party-perfect pieces, but you'll also be able to scoop up armfuls of them at 25 percent off when you use your BananaCard, GapCard, or OldNavyCard. Add to that a 35 percent discount on all non-Milly, Banana Republic finds and a special gift for all BananaCard Luxe members, and it's a hot night in the city.

Where, you ask, does one RSVP for drinks and shopping with Connie? No need, friends. The doors are open wide to you and all your besties! Just bring your purse and a healthy appetite for summer style.
